Composite (Multi-Function) Devices Might Appear in the Device List as More than One Device (1003778)
Some composite (multi-function) devices might appear in the device list as more than one device. An Apple Nano iPod, for example, is a mass storage device as well as a music player, and therefore appears as two devices.
Sharing one of these device listings will enable the entire device's functionality. If the device is not fully functional after you share one device listing, unshare that listing and share the other listing for the device.
